[0029] Reference Figure 1 , Figure 2and Figure 3 This utility model proposes a track-changing mechanism, mainly composed of a support platform 300 and a drive assembly 330. It features a simple structure and is easy to install and maintain. Specifically, the support platform 300 is the main support component of the track-changing mechanism, on which a first track 310 is mounted. The specifications and shape of the first track 310 match the main track 100 and the auxiliary track 200 to ensure that the circular track vehicle can smoothly switch between the first track 310, the main track 100, and the auxiliary track 200. It should be noted that the support platform 300 is made of high-strength material and has sufficient load-bearing capacity to withstand the weight of the circular track vehicle and its transported goods, ensuring that it will not deform or be damaged during track switching.
[0030] The drive assembly 330 is used to drive the support platform 300 to move, so that the first track 310 is connected to the main track 100 or the auxiliary track 200. The drive assembly 330 can adopt various driving methods, such as electric drive, hydraulic drive, etc. In this embodiment, an electric drive method is adopted, which has the advantages of smooth driving, high control precision, and fast response speed.
[0031] In a specific embodiment, when the circular track vehicle needs to switch from the main track 100 to the secondary track 200, the control unit receives the switching signal and controls the drive assembly 330 to start, driving the support platform 300 to move. When the support platform 300 moves to a predetermined position, precisely connecting the first track 310 and the secondary track 200, the control unit controls the motor 331 to stop rotating, and the support platform 300 stops moving. At this time, the circular track vehicle can smoothly move from the main track 100 into the first track 310, and then into the secondary track 200. When the circular track vehicle needs to switch back from the secondary track 200 to the main track 100, the working process is similar to the above process, except that the direction of movement of the support platform 300 is reversed.
[0032] Understandably, the track-changing mechanism of this utility model enables rapid track switching between the main track 100 and the auxiliary track 200 for the circular railcar without stopping the operation of the entire transportation system, greatly shortening the track-changing time and improving production efficiency. Furthermore, its simple structure facilitates installation and maintenance, reducing costs. By precisely controlling the drive component 330, the carrying platform 300 can move accurately, ensuring precise connection between the first track 310 and the main track 100 or the auxiliary track 200, avoiding problems such as bumps and derailment during track switching, thus improving the safety and stability of the circular railcar operation. Moreover, the track-changing mechanism can be flexibly adjusted according to different track layouts and specifications, making it suitable for various application scenarios and improving the mechanism's versatility and adaptability.
[0033] Reference Figure 1In some embodiments, the first track 310, main track 100, and auxiliary track 200 of the track-changing mechanism are all manufactured using high-precision machining processes. During installation, a laser rangefinder is used to precisely measure and adjust the gaps between the first track 310 and the main track 100 and auxiliary track 200. After multiple measurements and fine adjustments, it is ensured that the gaps between the first track 310 and the main track 100 and auxiliary track 200 all meet the requirement of not exceeding 1mm. Furthermore, the main track 100, auxiliary track 200, and first track 310 are all made of high-strength steel, and their surfaces undergo special treatment to improve wear resistance and corrosion resistance.
[0034] The smaller track clearance significantly reduces the impact and vibration between the wheels and the rails when the circular railcar switches tracks, effectively protecting goods from damage and reducing wheel wear, thus extending wheel life. Furthermore, precise track clearance control helps improve the positioning accuracy of the circular railcar, enabling it to stop more accurately at designated locations, thereby improving the overall operational efficiency and reliability of the transportation system.
[0035] In some embodiments, the main track 100 is used to carry multiple circular railcars and is the main operating track of the circular railcar transportation system. The auxiliary track 200 serves as a buffer for the circular railcars. When the circular railcars need to be inspected, maintained, or their operating routes adjusted according to production needs, they can be transferred from the main track 100 to the auxiliary track 200. Simultaneously, the main track 100, auxiliary track 200, and first track 310 all adopt an "I"-shaped structure to ensure sufficient load-bearing capacity and stability. The "I"-shaped structure has good load-bearing capacity and stability, capable of supporting the weight of the circular railcars and the goods they transport, reducing the risk of track deformation and damage, and improving the service life of the tracks.
[0036] Understandably, the main track 100 can carry multiple circular railcars simultaneously, while the secondary track 200 can buffer some of the circular railcars, allowing the transportation system to flexibly adjust the distribution of the circular railcars according to actual needs, thereby improving transportation efficiency.
[0037] Reference Figure 2 and Figure 3The track-changing mechanism proposed in this utility model also includes a second track 320. Specifically, the second track 320 is a steel track, arranged perpendicularly to the first track 310, allowing the carrying platform 300 to move smoothly on the second track 320. The arrangement of the second track 320 enables the carrying platform 300 to perform track switching operations at different positions, improving the flexibility and applicability of the track-changing mechanism and meeting the transportation needs in different scenarios. Furthermore, the vertical second track 320 can be flexibly set according to the warehouse layout and transportation requirements, optimizing the layout of the entire transportation system. Optionally, limit devices are provided at both ends of the second track 320 to prevent the carrying platform 300 from sliding off the track.
[0038] In a specific embodiment, the second track 320 is an "I"-shaped slide rail made of aluminum alloy, characterized by its light weight and high strength. A guide slider is installed at the bottom of the support platform 300, which fits tightly with the "I"-shaped slide rail. During installation, adjusting the gap between the guide slider and the slide rail ensures that the support platform 300 can move smoothly and steadily on the second track 320. It is easy to understand that the "I"-shaped slide rail and guide slider have a simple structure, are easy to install and maintain, and reduce costs. The guide slider, engaged with the second track 320, guides the support platform 300 to move along a predetermined path, preventing deviation or swaying during movement and improving the stability of the circular track vehicle during track changing.
[0039] Reference Figure 2 and Figure 3 The drive assembly 330 of the track-changing mechanism consists of an active component, a driven component, and a passive component. In some embodiments, the active component is a motor 331, the transmission component is a gear 332, and the passive component is a rack 333. The motor 331 is fixed to the support platform 300 by bolts, the gear 332 is mounted on the output shaft of the motor 331, and the rack 333 is fixed to the track foundation or track support. When track switching is required, the motor 331 starts, driving the gear 332 to rotate. The gear 332 meshes with the rack 333, causing the support platform 300 to move along the second track 320, thus switching the first track 310 with the main track 100 or the auxiliary track 200. The gear 332 and rack 333 transmission method has the characteristics of high transmission efficiency and high positioning accuracy, enabling precise control of the movement of the support platform 300 and ensuring precise connection between the first track 310 and the main track 100 or the auxiliary track 200. Furthermore, during the transmission process, the meshing of gear 332 and rack 333 is smooth, reducing vibration and noise, and improving the smoothness and reliability of the track-changing mechanism.
[0040] In other embodiments, the driving component is a hydraulic pump station, including a hydraulic pump, a motor 331, an oil tank, and a hydraulic valve assembly. The transmission component is a hydraulic cylinder, and the driven component is a stop block or fixed bracket mounted on the track, serving as a reference for the end point of the piston rod's extension and retraction stroke, indirectly assisting in the positioning of the support platform 300. When it is necessary to drive the support platform 300 to move, the hydraulic pump operates, pressing hydraulic oil into the rodless chamber of the hydraulic cylinder, pushing the piston rod to extend or retract, thereby driving the support platform 300 to move along the second track 320. When the support platform 300 moves to the designated position, the hydraulic valve assembly controls the pressure holding of the hydraulic cylinder, allowing the support platform 300 to stably stop at that position. The hydraulic drive can provide a large driving force, easily pushing the heavy-duty support platform 300 to move. It is suitable for large track-changing mechanisms with high load-bearing capacity requirements, relatively slow operating speeds, and large driving forces. Furthermore, the hydraulic drive has good buffering performance, enabling the support platform 300 to be more stable during start-up, stopping, and operation, reducing impact on the track and equipment.
[0041] Reference Figure 2 and Figure 3 In some embodiments, the track-changing mechanism is equipped with a positioning component 400. A mounting rod 410 is fixed to the track foundation or track support. A sensing component 420, employing a high-precision laser sensor, is mounted on the mounting rod 410 and can accurately measure the relative position of the first track 310 with the main track 100 and the auxiliary track 200. A controller is installed in the electrical control cabinet and is electrically connected to the drive component 330 and the sensing component 420 via cables. When the support platform 300 moves, the laser sensor monitors the relative position information of the first track 310 with the main track 100 and the auxiliary track 200 in real time and transmits the data to the controller. When the first track 310 is precisely connected to either the main track 100 or the auxiliary track 200, the controller receives the signal and immediately controls the drive component 330 to stop operating. The positioning component 400 enables automated control of the track-changing mechanism, reduces manual intervention, and improves the efficiency and accuracy of track changing.
[0042] In a specific embodiment, the mounting rod 410 serves as a support structure for the sensing component 420, providing mechanical strength and stability. The sensing component 420 may employ two inductive proximity switches, respectively mounted on both sides of the mounting rod 410, to detect the docking position of the first track 310 with the main track 100 and the auxiliary track 200. Alternatively, a pressure sensor may be used to detect the track docking pressure, ensuring the reliability of the mechanical connection. When the first track 310 docks with either the main track 100 or the auxiliary track 200, the metal plate on the track surface enters the sensor's detection range, triggering a high-level signal. When both inductive sensors trigger high-level signals, and the pressure sensor voltage is ≥5V, the track docking is considered complete. In other embodiments, the sensing component 420 may also integrate an industrial camera, achieving visual-assisted positioning through deep learning algorithms.
[0043] This utility model also proposes a circular railcar transportation system, comprising one or more track-changing mechanisms as described above. The track-changing mechanisms are rationally installed and configured according to cargo transportation needs and warehouse layout, enabling centralized management and scheduling. When cargo needs to be transported, the control system automatically plans the circular railcar's route based on the cargo's storage location and destination, and uses the track-changing mechanisms to switch the circular railcar between different tracks, completing the cargo transportation and storage tasks. Furthermore, when the circular railcar requires maintenance, upkeep, or repair, the track-changing mechanisms perform real-time track-changing buffering or directly guide it to the maintenance station, simplifying the maintenance and upkeep process and facilitating its use.
[0044] This utility model also proposes a storage device, which includes the circular railcar transportation system described above. By applying the aforementioned track-changing mechanism, the circular railcar in the storage device can be flexibly adjusted according to actual needs, improving the flexibility of cargo transportation. Furthermore, by achieving rapid, stable, and reliable track switching between the main track 100 and the auxiliary track 200, the maintenance and upkeep procedures of the circular railcar are simplified.
[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
